HackerRank Exceptions problem solution in Python

HackerRank Exceptions Python Solution – In this HackerRank Exceptions problem solution in Python, Errors detected during execution are called exceptions.

Examples:

ZeroDivisionError
This error is raised when the second argument of a division or modulo operation is zero.

>>> a = '1'
>>> b = '0'
>>> print int(a) / int(b)
>>> ZeroDivisionError: integer division or modulo by zero

ValueError
This error is raised when a built-in operation or function receives an argument that has the right type but an inappropriate value.

>>> a = '1'
>>> b = '#'
>>> print int(a) / int(b)
>>> ValueError: invalid literal for int() with base 10: '#'

_{Handling Exceptions}

The statements try and except can be used to handle selected exceptions. A try statement may have more than one except clause to specify handlers for different exceptions.

#Code
try:
    print 1/0
except ZeroDivisionError as e:
    print "Error Code:",e

Output

Error Code: integer division or modulo by zero

Task

You are given two values a and b.
Perform integer division and print a/b.

for t in xrange(int(input())):
    try:
        a,b = map(int,raw_input().split())
        print a/b
    except ZeroDivisionError as e:
        print "Error Code: %s" % e
    except ValueError as e:
        print "Error Code: %s" % e
